This study was conducted to study the antifungal effects of graphene nanoparticles on Aspergillus niger and Penicillium citrinum. Different concentrations of graphene nanoparticles were investigated to determine the minimum inhibitory concentration (MIC), the minimum fungicidal concentration (MFC) and inhibition zone diameter. The results showed that the concentration of graphene nanoparticle which inhibited the growth of Penicillium mold was statistically more than that of Aspergillus niger. On the other hand, there was no difference between the concentrations of MFC for these two fungi. The MIC results for Aspergillus niger and Penicillium citrinum were 10388.9 and 10527.8 μg/ml respectively. Evaluation of the growth inhibition zone showed that up to 10500 ppm, there was no difference between the inhibition zones diameter of two microorganisms. However, with an increase in the concentration of graphene nanoparticle, the difference between the zone diameters in the two molds increased, so that the diameter of the inhibition zone of Aspergillus niger in higher nanoparticle concentrations was more than that of Penicillin citrinum. According to the results of this study it can be concluded that the effect of graphene nanoparticles on Aspergillus niger was higher than that of Penicillin citrinum.
